Definitions

  • the invention relates to a household refrigerator with a fresh food container.
  • Food containers are known from the prior art, in which introduced food can be acted upon depending on a position of the lid relative to the shell with a different moisture content.
  • Such containers are for example from the WO 2011/026749 A2 or the DE 40 40 341 C2 known.
  • An inventive household refrigerator has a receiving space for food, in which a freshness container is arranged.
  • the food storage container comprises a tray and a lid which can be placed in a sealing manner on the tray.
  • An essential idea of the invention lies in the fact that the freshness-keeping container has a mechanically operating vacuum-generating unit, with which in the freshness-keeping container a reduced air pressure relative to the environment outside the fresh-food container can be set.
  • the vacuum generating unit has at least one actuating element, which is mechanically movable relative to the freshness holding container and thus in particular only mechanically actuated, and wherein depending on the movement of this actuating element air from the freshness holding container for adjusting the reduced air pressure can be sucked.
  • the vacuum generating unit is coupled to the shell such that depending on the movement of the shell, the actuating element of the vacuum generating unit is automatically actuated, in particular exclusively mechanically actuated.
  • an automatic mechanism for producing negative pressure by the movement of a component of the fresh food container, namely the bowl itself, is produced, without a user having to grasp and move the actuating element directly.
  • this generation of negative pressure for need-based storage of the food can not be forgotten, and thus has corresponding advantages in comparison with embodiments in which the actuating element must be actively actuated and displaced directly by a user in order to generate the negative pressure.
  • a piston of the vacuum generating unit is fixedly arranged in the receiving space and a piston housing accommodating the piston Vacuum generating unit is fixedly connected to the shell, wherein depending on the movement of the shell, the piston housing is displaceable relative to the piston and thereby air from the freshness holding container is sucked or inflated.
  • the vacuum generating unit has a linearly displaceable piston as an actuating element.
  • a simple actuation path of the actuating element is predetermined by such a straight-line displacement movement, thereby avoiding unwanted jamming or spreading.
  • the extraction of air volume from the fresh food container to produce a reduced air pressure is thus very uniform and continuously possible.
  • Due to the design of the actuating element as a piston a slider is also provided, which relatively quickly allows a relatively large volume from the fresh container for suction.
  • such a piston is also a mechanically stable component, which withstands the forces and stresses permanently and even with a more reduced pressure setting in the freshness container withstands these requirements and does not allow leaks.
  • the vacuum generating unit is designed as a mechanically operating pump, which in particular works exclusively mechanically, and has an actuating element designed as a piston, said piston being displaceably mounted in an actuating element housing of the pump designed as a piston housing. Depending on the displacement of the piston, the air can then be sucked out of the freshness-keeping container in order to set the reduced air pressure there.
  • a mechanically operating pump which in particular works exclusively mechanically
  • the piston being displaceably mounted in an actuating element housing of the pump designed as a piston housing.
  • the air can then be sucked out of the freshness-keeping container in order to set the reduced air pressure there.
  • the piston is also protected and surrounded and can also be guided precisely and accurately by the piston housing, so that, in particular, the linear displacement of the piston is achieved particularly advantageously.
  • the piston housing can be sucked by this design with a piston housing and the desired amount of air quickly and circumferentially, and by the specific leadership of the piston in the piston housing occur even with extensive air extraction from the fresh container no leakage.
  • the vacuum generating unit is integrated in the fresh food container.
  • a very compact position tolerance-free module can thus be created, as it were.
  • the coupling is thus already integrated, and there are extremely short distances between the vacuum generating unit and the fresh food container, so that the suction can be done very quickly and thus directly.
  • the negative pressure generating unit can be detachably detached from the freshness-keeping container in a non-destructive manner and reattached. This is advantageous in that for assembly purposes or maintenance accessibility to the shell and / or the lid on the one hand and to the vacuum generating unit on the other hand is improved. In particular, an advantage can also be achieved for cleaning purposes of said components.
  • the vacuum generating unit is received or arranged in a niche of the fresh food container.
  • a very compact design of this module can be achieved and the vacuum generating unit can also be arranged protected to some extent.
  • the negative pressure generating unit in this niche is received or arranged without overhang with respect to the dimensions of the fresh food container.
  • the niche is dimensioned such that, in the state of the vacuum generating unit arranged therein, this vacuum generating unit does not exceed the dimensions of the niche and thus also of the niche Holding fresh container and thus arranged quasi sunk.
  • this niche is formed in the shell of the fresh food container.
  • the vacuum generating unit is arranged below the shell. It may be arranged in the context, for example, at a bottom of the shell.
  • the negative pressure generating unit viewed in the horizontal direction, is arranged laterally next to a side wall of the shell, in particular being arranged adjacent to this side wall.
  • an individual freshness container can be created as needed.
  • the actuating element is accessible from the front of the fresh food container and is exposed and thus virtually this actuating element can be actuated via a front of the fresh food container.
  • a fresh container this actuator is arranged as a user-palpable slide, wherein depending on a user initiated by a movement of the actuating element then automatically air from the freshness container and thus from the through the shell and the volume sealingly limited thereto can be sucked off. If this actuator is then operated by a user again actuated in the opposite direction, the generated negative pressure or the reduced air pressure is canceled again and thus quasi air is introduced into the preservation container. This is also done exclusively by the mechanically operating vacuum generating unit.
  • the vacuum generating unit is arranged at a certain distance and thus without contact or contact with the shell and / or the lid and is connected via a, in particular flexible, air duct with an opening, in particular in the shell, then the suction of the air too enable.
  • This embodiment is advantageous if the volume of the fresh food container for receiving the food should remain unchanged and in the context, for example, no niche, as mentioned and explained above, should be present.
  • the freshness-keeping container has a display unit which is arranged on the shell and / or the lid and which is designed to display the air pressure in the freshness-keeping container.
  • the display can be done here, for example, by stationary and invariable symbols, which are applied for example as printing. Depending on the respective position of the actuating element relative to these stationary mounted elements or symbols then the respectively set air pressure can be detected in the fresh food container.
  • it can also be an electronic display, in which the air pressure, for example by means of a sensor, is detected and then displayed accordingly on a display of the display unit.
  • the freshness-keeping container can be removed without destruction in the receiving space.
  • the cover of the fresh food container can be lifted as a complete part of the shell or only a portion of the lid, for example as a flap, is formed, which can then be moved relative to the shell.
  • additional sealing elements are provided for sealingly placing the lid on the shell, for example, latching elements to the mechanically stable and sealing seat of the lid on the Favoring shell.
  • at least the shell is formed of a thin-walled and / or transparent plastic material.
